Europe's forests are suffering in silence. While an unregulated climate is increasing the number of large fires, causing parasites to multiply and creating droughts, the current late heatwave is further weakening trees that have been dying off en masse in recent years. But all is not lost: to survive, our forested areas will need to diversify and transform into "mosaics"  more resistant species, explains Albert Maillet, director of forests and climate risks at the National Forestry Office (ONF). lands. The forest is exposed to severe climatic stress. It is a silent storm: the damage is significant, although less noticeable than that caused in a single night by a historic storm. It is a long process, a storm with no end in sight. (Anne-Laure Barret and Margaux Lacroux)
